Coupling arrangement between a linear control element and a pivotable element, especially a control surface

Abstract

A coupling arrangement between a linear control element and a pivoting element, especially for an aerodynamic control surface of a guidable missile. The coupling arrangement has the pivoting element equipped with a pivot arm which extends radially from its axis of rotation, wherein the pivot arm is oriented transverse to the sliding or thrust axis of the control element which, in turn, is oriented transverse to the axis of rotaion, and in which the pivot arm stands in engagement with the control element.

What is claimed is: 
     
       1. In a coupling arrangement between a linear control element and a pivoting element, especially for an aerodynamic control surface of a guidable missile; the improvement comprising: said pivot element including a pivot arm radially projecting from the axis of rotation of said pivoting element, said pivot arm being oriented transverse to the sliding axis of the linear control element, said control element being oriented transverse to the axis of rotation of said pivoting element, said pivot arm being in engagement with said linear control element, said pivot arm engaging tangentially on both sides of a recess formed in said control element, said recess being formed in the head portion of a hollow cylinder engaging sleeve-like over the end of the control element and including an internal adjusting screw thread which is screwed onto an external screw thread on the the control element. 
     
     
       2. In a coupling arrangement between a linear control element and a pivoting element, especially for an aerodynamic control surface of a guidable missile; the improvement comprising: said pivot element including a forked pivot arm radially projecting from the axis of rotation of said pivoting element, said pivot arm being oriented transverse to the sliding axis of the linear control element, said control element being oriented transverse to the axis of rotation of said pivoting element, said pivot arm being in engagement with said linear control element, said forked pivot arm engaging tangentially on both sides of a recess formed in said control element, said recess being formed in the head portion of a hollow cylinder which engages sleeve-like over the end of the control element. 
     
     
       3. A coupling arrangement as claimed in claim 1 or 2, comprising surfaces contacting each other in the region of engagement of said control element with the pivot arm in every direction of movement of the control element, at least one said surface being spherically convexly shaped in the region of said axis of the control element. 
     
     
       4. A coupling arrangement as claimed in claim 1, wherein the pivot arm has a forked shape. 
     
     
       5. A coupling arrangement as claimed in claim 1 or 2, in which the recess is formed between an end surface of the control element and a screwhead of a screw arranged axially ahead thereof. 
     
     
       6. A coupling arrangement as claimed in claim 1 or 2, wherein a counterscrew passes through the hollow cylinder with the recess in the head portion thereof extending in parallel with the longitudinal axis of the arrangement, said counterscrew being screwed into the end surface of said linear control element.
